Reply to Traktor Gain Question

so recently i've been mixing with limiter and auto gain off... and -10 on master/main gain.

my question is, is it ok if the fader channel meters are hitting red but the master/main gain meter isnt? or should i be keeping the channel fader meters out of the red completely? I notice that a track "sometimes" would be hitting the red while playing in the middle of the track every now and then.

I ask because I want the track to be at its highest gain for quality but out of red due to clipping.

Is it better to keep autogain and limiter on?
